RELATED APPLICATION

This application claims priority to U.S. Provisional Application No. 61/760,776 filed Feb. 5, 2013, entitled, “Method and Apparatus for a Slider Interface Element,” which is incorporated herein by reference in its entirety.

TECHNICAL FIELD

The present application relates generally to a user interface.

BACKGROUND

As electronic apparatuses have expanded their capabilities, as well as the number and types of operations they perform, interaction has become increasingly complex and time consuming. For example, apparatus interaction may be prone to errors, confusion, and delay. In some circumstances, a user may miss an opportunity to do something, such as capture an image of an event, due to delays associated with interaction. In other circumstances, a user may avoid utilizing an apparatus capability due to a desire to avoid errors, confusion, or delay. These problems may be more pronounced with regard to a user controlling assignment of values to settings. Under such circumstances, it may be desirable for a user to be able to assign values to settings in a simple, quick, and intuitive manner.

A touch sensor, such as touch sensor 13A, and a display, such as display 14A, may be characterized as a touch display. In an embodiment comprising a touch display, the touch display may be configured to receive input from a single point of contact, multiple points of contact, and/or the like. In such an embodiment, the touch display and/or the processor may determine input based, at least in part, on position, motion, speed, contact area, and/or the like.

The electronic apparatus 10 may include any of a variety of touch displays including those that are configured to enable touch recognition by any of resistive, capacitive, infrared, strain gauge, surface wave, optical imaging, dispersive signal technology, acoustic pulse recognition or other techniques, and to then provide signals indicative of the location and other parameters associated with the touch. Additionally, the touch display may be configured to receive an indication of an input in the form of a touch event which may be defined as an actual physical contact between a selection object (e.g., a finger, stylus, pen, pencil, or other pointing device) and the touch display. Alternatively, a touch event may be defined as bringing the selection object in proximity to the touch display, hovering over a displayed object or approaching an object within a predefined distance, even though physical contact is not made with the touch display. As such, a touch input may comprise any input that is detected by a touch display including touch events that involve actual physical contact and touch events that do not involve physical contact but that are otherwise detected by the touch display, such as a result of the proximity of the selection object to the touch display. A touch display may be capable of receiving information associated with force applied to the touch screen in relation to the touch input. For example, the touch screen may differentiate between a heavy press touch input and a light press touch input. In at least one example embodiment, a display may display two-dimensional information, three-dimensional information and/or the like.

In embodiments including a keypad, the keypad may comprise numeric (for example, 0-9) keys, symbol keys (for example, #, *), alphabetic keys, and/or the like for operating the electronic apparatus 10. For example, the keypad may comprise a conventional QWERTY keypad arrangement. The keypad may also comprise various soft keys with associated functions. In addition, or alternatively, the electronic apparatus 10 may comprise an interface device such as a joystick or other user input interface.

Input devices 13 may comprise a media capturing element. The media capturing element may be any means for capturing an image, video and/or audio for storage, display or transmission. For example, in an example embodiment in which the media capturing element is a camera module, such as camera module 13B, the camera module may comprise a digital camera which may form a digital image file from a captured image. As such, the camera module may comprise hardware, such as a lens or other optical component(s), and/or software necessary for creating a digital image file from a captured image. Alternatively, the camera module may comprise only the hardware for viewing an image, while a memory device of the electronic apparatus 10 stores instructions for execution by the processor 11 in the form of software for creating a digital image file from a captured image. In an example embodiment, the camera module may further comprise a processing element such as a co-processor that assists the processor 11 in processing image data and an encoder and/or decoder for compressing and/or decompressing image data. The encoder and/or decoder may encode and/or decode according to a standard format, for example, a Joint Photographic Experts Group (JPEG) standard format.

FIGS. 2A-2I are diagrams illustrating a curvilinear slider interface element according to at least one example embodiment. The examples of FIGS. 2A-2I are merely examples of a curvilinear slider interface element, and do not limit the scope of the claims. For example, eccentricity of the curvilinear slider interface element may vary, position of the curvilinear slider interface element may vary, and/or the like.

In at least one example embodiment, a slider interface element relates to an interface element that allows a user to adjust a setting. In at least one example embodiment, the slider interface element relates to a linear shape where values of the setting are associated with various positions along the contour of the linear shape. In at least one example embodiment, there is a selection point associated with the slider interface element. The selection point may be utilized in conjunction with the slider interface element such that position of the selection point along the contour of the slider interface element may identify a value associated with the setting. Therefore, a user may cause adjustment of a setting by way of causing a change in the position of a selection point relative to a slider interface element. In such circumstances, an apparatus may determine a value of the first setting is based, at least in part, on a position of the first selection point relative to the slider interface element. For example, the apparatus may correlate position of the selection point along the contour of the slider interface element with the arrangement of values along the contour of the slider interface element to determine the value.

In at least one example embodiment, a user may perform one or more inputs to manipulate a slider interface element displayed by an apparatus. The apparatus may receive an indication of an input indicating manipulation of a slider interface element, for example by way of touch sensor 13A. In at least one example embodiment, the indication of the input relates to any communication that the input occurred, such as a message, a function call, modification of a variable, and/or the like.

In at least one example embodiment, the apparatus receives an indication of a drag input associated with a slider interface element. In at least one example embodiment, a drag input relates to a combination of a contact input, a movement input, and a release input. In at least one example embodiment, a contact input may relate to contact with a touch display, an input indicating selection associated with a cursor, for example using a mouse, and/or the like. The contact input may serve as designation of an interface element to be associated with the drag input. For example, if the contact input has a position correlating to a position of a slider interface element selection point, the contact input may be interpreted to indicate that the movement input of the drag input is associated with the slider interface element selection point. In at least one example embodiment, the movement input relates to any movement input in association with the drag input. Movement input may relate to movement of a touch input across the surface of a touch display, movement of a cursor, for example by a mouse, and/or the like. In at least one example embodiment, the release input relates to an input indicating termination of the drag input. For example, the release input may relate to removal of contact with a touch display, a termination of a button press, and/or the like. Even though the movement input may relate to movement in relation to multiple degrees of freedom, the apparatus may utilize a subcomponent of the movement input to adjust a slider interface element. For example, the apparatus may determine a projection of the movement input along the contour of the slider interface element to determine an effect of the movement input regarding the slider interface element.

In at least one example embodiment, an apparatus may provide a slider interface element upon determination to provide for adjustment of a setting associated with the slider interface element. For example, the apparatus may determine to provide for adjustment of the setting, and cause display of the slider interface element to enable the adjustment. In at least one example embodiment, causing display relates to performing an operation that results in information, such as a slider interface element, being displayed. For example, if the apparatus comprises a display, causing display of information may comprise displaying the information. In another example, causing display of information may comprise sending the information to a separate apparatus for displaying, such as a separate display.

The contour of a slider interface element may vary. In at least one example embodiment, it may be desirable to provide for a curvilinear slider interface element. In at least one example embodiment, a curvilinear slider interface element has a terminus at each end. For example, the curvilinear slider interface element may be bounded by a boundary of a display region, for example, by the boundary of a window, by the boundary of a display, and/or the like, such that at least one terminus corresponds with a display region boundary. In another example, the curvilinear slider interface element may be unbounded by a boundary of a display region, such that at least one terminus is within the display boundary region.

In at least one example embodiment, a curvilinear slider interface element is an elliptical slider interface element. In at least one example embodiment, an elliptical slider interface element is a circular slider interface element. In at least one example embodiment, the elliptical slider interface element relates to a partial ellipse. For example, the elliptical slider interface element may relate to a segment of an ellipse. The segment may be less that the entirety of the ellipse. For example, the elliptical slider interface element may be bounded by a boundary of a display region, for example, by the boundary of a window, by the boundary of a display, and/or the like. In another example, the elliptical slider interface element may be unbounded by a boundary of a display region, but still relate to less than the entirety of an ellipse.

In at least one example embodiment, an elliptical slider interface element varies insubstantially from an ellipse. In at least one example embodiment, insubstantial variation relates to a variation that is not relevant to a user's ability to perceive similarity between the curvilinear slider interface element and an ellipse. For example, pixilation associated with display of the elliptical slider interface element may cause the curvilinear slider interface element to insubstantially vary from an ellipse. In at least one example embodiment, variation of a elliptical slider interface element from an ellipse is insubstantial if the elliptical slider interface element provides for perception of an elliptical property. In at least one example embodiment, an elliptical property relates to the elliptical slider interface element being perceived to have foci, to have a shape consistent with curvature around at least one point, and/or the like.

Without limiting the claims in any way, at least one technical effect associated with a curvilinear slider interface element is that the curvilinear contour allows for ergonomically simple utilization under many circumstances. For example, when using a touch display, the touch gestures being performed may be based, at least in part, on the movements of the user's body. The user's body movement may be based, at least in part, on articulation of an appendage around a joint. Such articulation may often be curvilinear. This effect may be strengthened for handheld apparatuses, such as apparatus 500 of FIG. 5A or apparatus 550 of FIG. 5B. Such apparatuses are often held by the fingers and hand so that touch input is performed by the thumbs of the user. Under such circumstances, the curvilinear contour may provide a more ergonomically sound contour for a user to perform a drag input associated with adjustment of a curvilinear slider interface element. Furthermore, under such circumstances, a curvilinear drag input may be a more cognitively simple than straight drag input in that the user may be able to perform a curvilinear drag by variation of angle absent substantial variation in extension of the thumb. For example, the user may be able to trace an ellipse with the user's thumb without contracting the thumb. In at least one example embodiment, at least several technical effects associated with lack of change in thumb extension during a drag input may be reduced user tendency to drop the apparatus during the drag input, improved speed of the input, and simplified user motor coordination associated with input.

FIG. 2A is a diagram illustrating curvilinear slider interface element 202 in relation to display region 200, according to at least one example embodiment. In the example of FIG. 2A, curvilinear slider interface element 202 is concave towards the right boundary of display region 200. In at least one example embodiment, interface element 202 is an elliptical slider interface element having a foci proximate to the right boundary of display region 200. However, position of the foci may vary. For example, the foci may be positioned within display region 200, may be positioned beyond the boundary of display region 200, may be positioned beyond the apparatus, etc. For example, the foci may be positioned at a point beyond the apparatus that corresponds with an average position of a thumb joint when the apparatus is held by a user. It can be seen that curvilinear slider interface element 202 extends from one boundary of display region 200 to another boundary of display region 200. However, curvilinear slider interface element may have at least one terminus within the boundary of display region 200.

FIG. 2B is a diagram illustrating curvilinear slider interface element 222 in relation to display region 220, according to at least one example embodiment. In the example of FIG. 2B, indicators 230, 232, and 234 relate to representations indicating correlation of a position along the contour of the curvilinear slider interface element and a value represented by the indicator. In at least one example embodiment, a position along the contour of a slider interface element that is associated with a value may be referred to as a value position. Therefore, In at least one example embodiment, indicator 230 is caused to be displayed proximate to a value position associated with a value indicated by indicator 230, indicator 232 is caused to be displayed proximate to a value position associated with a value indicated by indicator 232, and indicator 234 is caused to be displayed proximate to a value position associated with a value indicated by indicator 234. In at least one example embodiment, indicators 230, 232, and 234 are oriented such that the base of the indicator aligns with the base of the display region. The base of the indicator relates to the bottom portion of the indicator when the indicator is shown in an upright representation. In at least one example embodiment, indicators 230, 232, and 234 are oriented such that the base of the indicator aligns with the contour of curvilinear slider interface element 222.

A value associated with a setting of a slider interface element may be a non-cardinal value. For example, the value may be a designation of a classification associated with the setting. In such an example, the value may indicate a classification such as automatic value determination, an algorithm associated with value determination, and/or the like, similar as described regarding FIG. 9. Therefore, at least one of representations 230, 232, and 234 may be a demarcation of an automatic adjustment selection.

FIG. 2C is a diagram illustrating curvilinear slider interface element 242 in relation to display region 240, according to at least one example embodiment. The example of FIG. 2C illustrates selection point 244 associated with curvilinear slider interface element 242. In at least one example embodiment, a selection point relates to an indicator that identifies a position along the contour of a slider interface element that corresponds with a selected value position. In at least one example embodiment, an apparatus determines a value of the setting that is associated with a slider interface element, such as a curvilinear slider interface element, based, at least in part, on the position of the selection point relative to the slider interface element. For example, the apparatus may correlate position of the selection point with a value position of the slider interface element, and determine the value based, at least in part, on a value associated with the value position.

In the example of FIG. 2C, indicators 250, 252, and 254 relate to representations indicating values associated with value positions of curvilinear slider interface element 242, similar as described regarding FIG. 2B. It can be seen that the position of indicator 252 is proximate to selection point 244 by way of being adjacent to selection point 244. In at least one example embodiment, indicator 252 comprises a representation of the value of the setting associated with curvilinear slider interface element 242. For example, indicator 252 may be a representation of the value associated with a value position that corresponds with selection point 252. In at least one example embodiment, indicators 250 and 254 are referred to as non-selected value information and indicator 252 is referred to as selected value information. In at least one example embodiment, selected value information differs from non-selected value information. For example, such difference may emphasize selected value information beyond the emphasis of non-selected value information. For example, non-selected value information may be oriented such that the base of the indicator aligns with the contour of curvilinear slider interface element 242, and selected value information may be oriented such that the base of selected value information aligns with the base of display region 240. In another example, selected value information may vary from non-selected value information by size, by color, by font, and/or the like.

In at least one example embodiment, selected value information may comprise an indication that the setting associated with a curvilinear slider interface element is subject to automatic adjustment. In such circumstances, selected value information may further comprise a representation of the value of the setting, i.e. the automatically selected value.

FIG. 2D is a diagram illustrating curvilinear slider interface element 242 in relation to display region 240, according to at least one example embodiment. In at least one example embodiment, an apparatus may cause movement of a selection point relative to a curvilinear slider interface element associated with the selection point. In at least one example embodiment, movement of a selection point relative to a curvilinear slider interface element associated with the selection point is referred to as adjustment movement. In at least one example embodiment, adjustment movement may be based, at least in part, on receipt of an indication of an input associated with the curvilinear slider interface element. For example, the input may be a drag input. In at least one example embodiment, the adjustment movement is based, at least in part, on receipt of an indication of a drag input. The drag input may comprise a contact input associated with the curvilinear slider interface element. In at least one example embodiment, the adjustment movement is in proportion to a movement input of the drag input. For example, the adjustment movement may be based, at least in part, on a projection of the movement input on the contour of the curvilinear slider interface element.

In at least one example embodiment, movement of the selection point relative to the curvilinear slider interface element relates to retaining position of a selection point associated with the curvilinear slider interface element. For example, the curvilinear slider interface element may move, and the selection point may be stationary. In at least one example embodiment, the movement of the selection point relative to the curvilinear slider interface element is characterized by rotating the first curvilinear slider interface element. For example, the curvilinear slider interface element may be rotated about a region that it is concave toward. In at least one example embodiment, rotation of the curvilinear slider interface element relates to movement of value positions along the contour of the curvilinear slider interface element.

The slider interface element may operate to provide an illusion of a continuous ellipse that is beyond the curvilinear slider interface element displayed to a user. For example, based, at least in part, on the movement of rotation of the curvilinear slider interface element, the curvilinear slider interface element may provide non-selected value information that was previously omitted. In another example, based, at least in part, on the movement of rotation of the curvilinear slider interface element, the curvilinear slider interface element may omit non-selected value information that was previously provided. The example of FIG. 2D illustrates curvilinear slider interface element 242 after adjustment movement from the representation illustrated in FIG. 2C. It can be seen that curvilinear slider interface element 242 has rotated counter clockwise, and selection point 244 has retained its position. Similarly, non-selected value information 250 has rotated in conjunction with the curvilinear slider interface element. It can be seen that indicator 252 has rotated in conjunction with curvilinear slider interface element 242. As such, indicator 252 fails to correlate with selection point 244, and is non-selected value information. It can be seen that, based, at least in part, on the movement of rotation of curvilinear slider interface element 242, curvilinear slider interface element 242 has provided non-selected value information 256, which was previously omitted.

In at least one example embodiment, the movement of the selection point relative to the curvilinear slider interface element associated with the selection point may be based, at least in part, on a determination that a value of the setting associated with the curvilinear slider interface element has changed. The value may have changed by way of automatic adjustment, by way of change by another program, by way of a directive to set the setting to a default value, and/or the like. Under such circumstances, the apparatus may cause the movement of the selection point relative to the curvilinear slider interface element associated with the selection point based, at least in part, on a determination that a value of the setting associated with the curvilinear slider interface element has changed. Such determination may be based, at least in part, on the apparatus performing the change, receiving a notification signifying the change, and/or the like. For example, the apparatus may be set to automatically adjust the setting. In such an example, the setting may relate to a focus setting, and the apparatus may be set to utilize automatic focus. In such an example, a change in focus associated with the automatic focus may be represented by an adjustment movement of the curvilinear slider interface element.

Without limiting the scope of the claims in any way, at least one technical effect associated with causing adjustment movement of the curvilinear slider interface element based, at least in part, on determination that the setting associated with the curvilinear slider interface element has changed may be to allow the user to perceive the change in the same manner as if the user had performed the change himself. This perception may be desirable to allow the user to better perceive the effect of a setting adjustment as the adjustment occurs without reading any indicator.

FIG. 2E is a diagram illustrating curvilinear slider interface element 242 in relation to display region 240, according to at least one example embodiment. The example of FIG. 2E illustrates curvilinear slider interface element 242 after adjustment movement from the representation illustrated in FIG. 2D. It can be seen that curvilinear slider interface element 242 has rotated counter clockwise, and selection point 244 has retained its position. Similarly, indicator 250 has rotated in conjunction with the curvilinear slider interface element. It can be seen that indicator 250 now correlates with selection point 244, and has become selected value information 250. It can be seen that, based, at least in part, on the adjustment movement of rotation of curvilinear slider interface element 242, curvilinear slider interface element 242 has omitted non-selected value information 254, which was previously provided.

FIG. 2F is a diagram illustrating curvilinear slider interface element 242 in relation to display region 240, according to at least one example embodiment. In at least one example embodiment, movement of the selection point relative to the curvilinear slider interface element relates to retaining position of a curvilinear slider interface element associated with the selection point. For example, the selection point may move, and the curvilinear slider interface element may be stationary. In at least one example embodiment, the movement of the selection point relative to the curvilinear slider interface element is characterized by movement of the selection point along the contour of the curvilinear slider interface element.

The example of FIG. 2F illustrates curvilinear slider interface element 242 and selection point 244 after adjustment movement from the representation illustrated in FIG. 2C. It can be seen that selection point 244 has moved counter clockwise along the contour of curvilinear slider interface element 242, and curvilinear slider interface element 242 has retained its position. As such, indicator 252 fails to correlate with selection point 244, and is non-selected value information.

FIG. 2G is a diagram illustrating curvilinear slider interface element 242 in relation to display region 240, according to at least one example embodiment. The example of FIG. 2G illustrates curvilinear slider interface element 242 and selection point 244 after adjustment movement from the representation illustrated in FIG. 2F. It can be seen that selection point 244 has moved counter clockwise along the contour of curvilinear slider interface element 242, and curvilinear slider interface element 242 has retained its position. It can be seen that indicator 250 now correlates with selection point 244, and has become selected value information 250.

It may be desirable to provide selected value information associated with a curvilinear slider interface element at a position relative to the curvilinear slider interface element such that the position does not vary in correspondence with adjustment movement of the curvilinear slider interface element. In at least one example embodiment, the selected value information may be positioned in correspondence with a midpoint of the curvilinear slider interface element, at a midpoint on an axis of a display region, and/or the like. Without limiting the scope of the claims in any way, at least one technical effect of such position retention may be to provide a user with a consistent location to expect to see selected value information with respect to a curvilinear slider interface element.

FIG. 2H is a diagram illustrating curvilinear slider interface element 262, selection point 264, and selected value information 272 in relation to display region 260, according to at least one example embodiment. The example of FIG. 2H selected value information 272 being adjacent to curvilinear slider interface element 262 at a midpoint of curvilinear slider interface element 262. It can be seen that selected value information 272 is at a midpoint of a vertical axis of display region 260.

FIG. 2I is a diagram illustrating curvilinear slider interface element 262, selection point 264, and selected value information 272 in relation to display region 260, according to at least one example embodiment. The example of FIG. 2I relates to the example of FIG. 2H after an adjustment movement of curvilinear slider interface element 262. In the example of FIG. 2I, selected value information 272 has retained its position. For example, position of value information 272 did not vary in correspondence with the adjustment movement of curvilinear slider interface element 262 illustrated in the example of FIG. 2I.

FIGS. 3A-3J are diagrams illustrating a curvilinear slider interface element according to at least one example embodiment. The examples of FIGS. 3A-3J are merely examples of a curvilinear slider interface element, and do not limit the scope of the claims. For example, eccentricity of the curvilinear slider interface element may vary, position of the curvilinear slider interface element may vary, and/or the like.

FIG. 3A is a diagram illustrating a plurality of curvilinear slider interface elements in relation to display area 300, according to at least one example embodiment. In at least one example embodiment, an apparatus causes display of a curvilinear slider interface element associated with a setting, and causes display of another curvilinear slider interface element associated with another setting. For example, curvilinear slider interface element 302 may be associated with one setting, and curvilinear slider interface element 306 may be associated with a different setting. In the example of FIG. 3A, selection point 308 is associated with curvilinear slider interface element 306, and selection point 304 is associated with curvilinear slider interface element 302.

In at least one example embodiment, a plurality of selection points are aligned along a common delineation. In at least one example embodiment, a plurality of selection points are aligned along an axis associated with a display region, such as a vertical axis, a horizontal axis, and/or the like. In at least one example embodiment, a plurality of selection points are aligned along an axis associated with a display region, such that the axis intersects a midpoint of the display region. In the example of FIG. 3A, selection points 304 and 308 are aligned along a horizontal axis associated with display region 300, such that the axis intersects the vertical midpoint of display region 300.

Without limiting the scope of the claims in any way, at least one technical effect associated with the plurality of selection points being aligned along a common delineation may be to allow the user to gaze across the selection points in a linear eye movement without directional changes. Without limiting the scope of the claims in any way, at least one technical effect associated with the plurality of selection points being aligned along a common delineation may be to allow the user to recognize that there is a relationship among the curvilinear slider interface elements. Without limiting the scope of the claims in any way, at least one technical effect associated with the plurality of selection points being aligned along an axis associated with a display region may be to allow the user to perceive the selection points as an extension of the geometry associated with the display region. Such perception may assist the user in locating and recognizing the selection points by way of extending the paradigm established by the geometry of the display area, so that the user interacts more quickly and/or makes fewer errors. Without limiting the scope of the claims in any way, at least one technical effect associated with the plurality of selection points being aligned along an axis associated with a display region, such that the axis intersects a midpoint of the display region may be to allow for similar visibility of the curvilinear slider interface element above and below the selection point. Such visibility may allow the user to perceive values indicators along the curvilinear slider interface element similarly in both directions, and thus may allow the user to perform input more quickly and/or with fewer errors.

In at least one example embodiment, a plurality of curvilinear slider interface elements have concavity towards a common region with differing distances from the region. In at least one example embodiment, a region extending from the curvilinear slider interface element in a direction towards which the curvilinear slider interface element is concave is referred to as a concavity region. In a least one example embodiment, curvilinear slider interface elements are referred to as being concentrically curvilinear if one curvilinear slider interface element is positioned such that another curvilinear slider interface element is within the concavity region of the curvilinear slider interface element.

In at least one example embodiment, a plurality of elliptical slider interface elements have common foci with differing distances from the foci are concentrically curvilinear. For example, one elliptical slider interface element may be based, at least in part, on an ellipse that has common foci with an ellipse which serves as the basis for another elliptical slider interface element. In other words, the plurality of elliptical slider interface elements may be concentrically elliptical. For example, the plurality of elliptical slider interface elements may be based, at least in part, on concentric ellipses.

Without limiting the scope of the claims in any way, at least one technical effect associated with the plurality of curvilinear slider interface elements being concentric may be to allow the user to recognize that there is a relationship among the curvilinear slider interface elements.

FIG. 3B is a diagram illustrating curvilinear slider interface element 312 and operation actuator 316 in relation to display region 310, according to at least one example embodiment.

In at least one example embodiment, a setting associated with a curvilinear slider interface element is associated with an operation. For example, the setting may be a setting that is utilized in association with performance of the operation. For example, the setting may influence performance of the operation in some way. For example, the operation may be an image capture operation and the setting may relate to a shutter speed setting.

In at least one example embodiment, an operation actuator, such as operation actuator 316, relates to a representation of the operation that allows the user to identify the operation. In at least one example embodiment, the operation actuator may relate to invocation of the operation associated with the operation actuator. For example, an apparatus may receive an input indicative of invocation of the operation, based, at least in part, on the input being related to the operation actuator. For example, the apparatus may determine to invoke an operation based, at least in part, on correlation between an input and the operation actuator. In at least one example embodiment, an input associated with causing invocation of an operation associated with an operation actuator is referred to as an actuation input. For example, a user tapping on a touch display at a position associated with an operation actuator may be an actuation input associated with the operation actuator. In at least one example embodiment, an apparatus may cause performance of the operation based, at least in part, on receipt of an indication of an actuation input associated with an operation actuator. In such an example, the operation may be performed in accordance with one or more settings associated with one or more curvilinear slider interface elements.

In the example of FIG. 3B, operation actuator 316 may be associated with an operation. In such an example, the operation may be associated with a setting. The setting may be associated with curvilinear slider interface element 312. In at least one example embodiment, performance of the operation associated with operation actuator 316 comprises performance of the operation in accordance with the setting associated with curvilinear slider interface element 312 having a value indicated by selection point 314.

In at least one example embodiment, an operation actuator is positioned within an ellipse associated with a curvilinear slider interface element. For example, operation actuator 316 is positioned within the ellipse of curvilinear slider interface element 312. Without limiting the claims in any way, at least one technical effect associated with an operation actuator being positioned within an ellipse associated with a curvilinear slider interface element may be to allow the user to recognize that there is a relationship between the curvilinear slider interface element and the operation actuator. For example, the user may be able to intuitively determine that a setting associated with curvilinear slider interface element 312 is associated with an operation indicated by operation actuator 316.

FIG. 3C is a diagram illustrating curvilinear slider interface elements 322 and 328 and operation actuator 326 in relation to display region 320, according to at least one example embodiment. In at least one example embodiment, an operation represented by an operation actuator has a plurality of associated settings. In such an embodiment, at least a portion of, the settings may relate to a plurality of curvilinear slider interface elements.

Without limiting the claims in any way, at least one technical effect associated with retaining position of curvilinear slider interface element in differing orientation relates to retaining a position that is convenient for thumb access. For example, as seen in FIG. 5A, in portrait orientation, positioning the curvilinear slider interface elements such that the concavity region is proximate to the bottom of the display region provides for easy thumb control. The proximity of the concavity region of the curvilinear slider interface elements to the bottom of the display region in portrait mode may provide proximity to the base of the thumb, which may allow for simplified thumb movement along the contour of the curvilinear slider interface element. Similarly, as seen in FIG. 5B, in landscape orientation, positioning the curvilinear slider interface elements such that the concavity region is proximate to the side of the display region provides for easy thumb control. The proximity of the concavity region of the curvilinear slider interface elements to the side of the display region in landscape mode may provide proximity to the base of the thumb, which may allow for simplified thumb movement along the contour of the curvilinear slider interface element.

The movement input may relate to an orthogonal direction from the curvilinear slider interface element by relating to an orthogonal direction from a tangent of the curvilinear slider interface element. In at least one example embodiment, such an input is an input indicative of a non-adjustment movement of the curvilinear slider interface element. Without limiting the claims in any way, at least one technical effect associated with the movement input being related to an orthogonal direction from the curvilinear slider interface element may be that such a movement input is more likely to be independent of adjustment movement of the curvilinear slider interface element.

In the example of FIG. 7E, the non-adjustment movement of curvilinear slider interface element may be characterized as a curvilinear contraction.

When a user performs input that causes non-adjustment movement of a curvilinear slider interface element from a first position to a second position, it may be desirable to position the curvilinear slider interface element back to the first position when the user terminates the input. For example, the user may desire to temporarily move the curvilinear slider interface element during adjustment to avoid the curvilinear slider interface element obscuring overlaid visual information. Under such circumstances, the user may desire the movement to only relate to the time period that the user is performing the adjustment so that the arrangement of a set of curvilinear slider interface elements is not effected beyond the time of the input.

In at least one example embodiment, the movement described regarding FIG. 7E may be related to the adjustment described regarding FIGS. 3I-J.

FIGS. 8A-8F are diagrams illustrating a curvilinear slider interface element according to at least one example embodiment. The examples of FIGS. 8A-8F are merely examples of a curvilinear slider interface element, and do not limit the scope of the claims. For example, eccentricity of the curvilinear slider interface element may vary, position of the curvilinear slider interface element may vary, and/or the like.

In some circumstances, a user may desire to flip a curvilinear slider interface element from one side of a display region to an opposite side of the display region. For example, the user may desire to move the concavity region of the curvilinear slider interface element from one side of the display region to the opposite side of the display region. For example, a user may desire such non-adjustment movement in a landscape orientation so that the user may control the setting with a thumb on the opposite side of the apparatus.

FIGS. 8A and 8B are a diagrams illustrating non-adjustment movement of a curvilinear slider interface element in relation to display area 800 according to at least one example embodiment.

In at least one example embodiment, a user may cause non-adjustment movement that relates to placement of a curvilinear slider interface element being positioned at an opposite side of a display region by way of performing a drag input associated with non-adjustment movement of the curvilinear slider interface element such that a movement input comprised by the drag input crosses a positional threshold. In at least one example embodiment, the positional threshold relates to a delineation that is parallel to the side of the display region. In at least one example embodiment, the delineation relates to a midpoint between the side of the display region and the opposite side of the display region.

The example of FIGS. 8A and 8B illustrates curvilinear slider interface elements 802, 812, and 822, selection points 804, 814, 824, operation actuator 806, and positional threshold 808. FIG. 8B illustrates the curvilinear slider interface elements 802, 812, and 822, selection points 804, 814, 824, operation actuator 806, and positional threshold 808 of FIG. 8A after performance of placement of curvilinear slider interface element 822 being positioned at the opposite side of display region 800. In the example of FIGS. 8A and 8B, the non-adjustment movement associated with placement of curvilinear slider interface element 822 may be based, at least in part, on receipt of the drag input associated with non-adjustment movement of curvilinear slider interface element comprising a movement input that crosses positional threshold 808. Placement of curvilinear slider interface element 822 may be characterized as placement at a position that is symmetrical to the position of curvilinear slider interface element 822 relative to the side of the display region as shown in FIG. 8A.

FIG. 8C is a diagram illustrating non-adjustment movement of a curvilinear slider interface element an operation actuator in relation to display area 800, according to at least one example embodiment.

In some circumstances, a user may desire to flip multiple curvilinear slider interface elements and an operation actuator from one side of a display region to an opposite side of the display region. For example, the user may desire to move the concavity region of multiple curvilinear slider interface elements from one side of the display region to the opposite side of the display region. For example, a user may desire such non-adjustment movement in a landscape orientation so that the user may control the settings with a thumb on the opposite side of the apparatus.

In at least one example embodiment, a user may cause non-adjustment movement that relates to placement of multiple curvilinear slider interface elements and an operation actuator being positioned at an opposite side of a display region by way of performing a drag input associated with movement of the operation actuator such that a movement input comprised by the drag input crosses a positional threshold. In at least one example embodiment, a drag input associated with an operation actuator relates to a drag input that comprises a contact input that corresponds with the operation actuator. In at least one example embodiment, the positional threshold relates to a delineation that is parallel to the side of the display region. In at least one example embodiment, the delineation relates to a midpoint between the side of the display region and the opposite side of the display region. Without limiting the claims in any way, at least one technical effect associated with such non-adjustment movement of curvilinear slider interface elements and an operation actuator based, at least in part, on such a drag input associated with an operation actuator may be that such non-adjustment movement may be intuitive to the user based, at least in part, on the operation actuator being represented as a visual core of the curvilinear slider interface elements. Such a representation provides the perception of dependency of the curvilinear slider interface elements upon the operation actuator. Therefore, based, at least, on this perception, it may be intuitive for a user to cause non-adjustment movement of the operation actuator and the curvilinear slider interface elements based, at least in part, on a drag input associated with movement of the operation actuator.

The example of FIGS. 8A and 8C illustrates curvilinear slider interface elements 802, 812, and 822, selection points 804, 814, 824, operation actuator 806, and positional threshold 808. FIG. 8C illustrates the curvilinear slider interface elements 802, 812, and 822, selection points 804, 814, 824, operation actuator 806, and positional threshold 808 of FIG. 8A after performance of placement of curvilinear slider interface elements 802, 812, and 822, and operation actuator 806 being positioned at the opposite side of display region 800. In the example of FIGS. 8A and 8B, the non-adjustment movement associated with placement of curvilinear slider interface elements 802, 812, and 822, and operation actuator 806 may be based, at least in part, on receipt of the drag input associated with non-adjustment movement of operation actuator 806 comprising a movement input that crosses positional threshold 808. Placement of curvilinear slider interface elements 802, 812, and 822, and operation actuator 806 may be characterized as placement at a position that is symmetrical to the position of curvilinear slider interface elements 802, 812, and 822, and operation actuator 806 relative to the side of the display region as shown in FIG. 8A.

FIG. 8D is a diagram illustrating a curvilinear slider interface element according to at least one example embodiment. In at least one example embodiment, it may be desirable to cause all of the settings associated with an operation to be set to default values. In at least one example embodiment, a default value relates to a value of a setting that is based, at least in part, on a predetermined value unmodified by a user. For example, a user may cause a change to a setting that has adverse effects. In such an example, the user may desire to have the setting revert back to its default value. In such an example, the user may desire to set all of the settings to a default value by way of a quick input.

In at least one example embodiment, a user may cause all of the settings associated with an operation actuator by performing a drag input associated with movement of the operation actuator such that the drag input comprises a release input associated with a default setting zone. In at least one example embodiment, the default setting zone is confined to be within a half of a display region that comprises the operation actuator. In at least one example embodiment, the apparatus may cause display of an indication of the default setting zone. An indication of the default setting zone may relate to a demarcation that allows a user to identify the default setting zone.

In the example of FIG. 8D a user may perform a drag input, associated with operation actuator 806, having a release input within default setting zone 810 to cause settings associated with curvilinear slider interface elements 802, 812, and 822 to be set to default values.

It may be desirable for a user to be able to hide curvilinear slider interface elements associated with an operation actuator. For example, a user may desire to hide the curvilinear slider interface element to reduce obscurance of information overlain by the curvilinear slider interface element. In such an example, it may be desirable for the user to be able to perform a simple input to hide and/or unhide the curvilinear slider interface elements.

In at least one example embodiment, a user may cause display of one or more curvilinear slider interface elements by performing an input, such as an input comprising a movement input, in association with an operation actuator associated with the curvilinear slider interface element. Without limiting the scope of the claims in any way, at least one technical effect associated with such causation may be to allow the user to easily remember how to invoke display of curvilinear slider interface elements associated with setting of the operation actuator. For example, the user may be aware of the relationship between the settings and the operation actuator. Such awareness may provide an instinctive recognition that performance of a movement input associated with the operation actuator may cause display of an interface for adjusting related settings. For example, the movement input may be perceived as a “shaking loose” or an “expansion” to the settings interface.

In at least one example embodiment, a movement input, for example a movement input comprised by a drag input, is associated with causation of display of one or more curvilinear slider interface elements associated with the operation actuator. In at least one example embodiment, causation of display of one or more curvilinear slider interface elements is based, at least in part, on a distance of the movement input being beyond a distance threshold. A distance threshold may be a distance beyond which movement input associated with an operation actuator is associated with invocation of displaying one or more curvilinear slider interface elements. In at least one example embodiment, the distance of the movement input being within the distance threshold is associated with abstinence from displaying one or more curvilinear slider interface elements.

In at least one example embodiment, causation of display of one or more curvilinear slider interface elements is based, at least in part, on a release input associated with the movement input being within a setting adjustment region. A setting adjustment region may be a region within which release input associated with an operation actuator is associated with invocation of displaying one or more curvilinear slider interface elements. In at least one example embodiment, the release input associated with the movement input being beyond the setting adjustment region is associated with abstinence from displaying one or more curvilinear slider interface elements.

FIG. 8E is a diagram illustrating operation actuator 856 and setting adjustment region 860 in relation to display region 850, according to at least one example embodiment. In at least one example embodiment, a user may perform a drag input associated with operation actuator 856 that comprises a release input within setting adjustment region 860 to cause display of one or more curvilinear slider interface elements. For example, a user may perform a drag input associated with operation actuator 856 that comprises a release input within setting adjustment region 860 to cause transition to the example of FIG. 8F.

In at least one example embodiment a user may perform in input associated with a setting adjustment termination region to cause termination of display of one or more curvilinear slider interface elements. For example, a user may perform an input comprising a release input within a setting adjustment termination region comprising a contact input within a setting adjustment termination region, and/or the like. For example, the input may be related to a tap input. In at least one embodiment, a tap input relates to an input comprising a contact input and a release input. A tap input may lack a movement input.

It may be desirable to reposition an operation actuator during a time when associated curvilinear slider interface elements are being displayed. For example a user may be able to better comprehend the relationship between the operation actuator and the curvilinear slider interface elements based on the repositioning. In at least one example embodiment, the operation actuator is repositioned to a position that is closer to a position of the curvilinear slider interface elements when the curvilinear slider interface elements are caused to be displayed. Without limiting the scope of the claims in any way, at least one technical effect of such positioning may be to provide an indication that a movement input may be associated with causing display of the curvilinear slider interface elements. For example a user may identify the repositioning of the operation actuator with a movement input.

FIG. 8F is a diagram illustrating curvilinear slider interface elements 852, 862, and 872, selection points 854, 864, 874, operation actuator 856, and setting adjustment termination region 855 in relation to display region 850, according to at least one example embodiment. In at least one example embodiment, a user may perform an input associated setting adjustment termination region 855 to cause termination of display of one or more curvilinear slider interface elements. For example, a user may perform an input associated setting adjustment termination region 855 to cause transition to the example of FIG. 8E. In at least one example embodiment, position of 856 is further from the right side of display region 850 in the example of FIG. 8F that in the example of FIG. 8E.

In at least one example embodiment, a setting may be capable of being adjusted based, at least in part, on more than one value position type. In at least one example embodiment a value position type relates to a manner in which value positions are distributed. For example, a value position type may be conducive to a continuous distribution of value positions and another value position type may be conducive to an indexed distribution of value positions. For example, a large range of values relative to the increment between values, such as a manual focus setting, may be conducive to a continuous distribution of value positions. In another example, a discrete set of enumerated values may be conducive to an indexed distribution of value positions.

In at least one example embodiment, a continuous distribution of value positions relates to a distribution of value positions such that separation between adjacent value positions is undesirable to perceive. For example, separation between adjacent value positions may be similar to a perceived discontinuity associated with graphics processing. In at least one example embodiment, a continuous distribution is a distribution of value positions relates to a distribution of value positions such that separation between adjacent value positions is less than 95% just-noticeable difference based, at least in part, on the length of a slider interface element associated with the setting.

In at least one example embodiment, an indexed distribution of value positions relates to a distribution of value positions such that separation between adjacent value positions such that separation between adjacent value positions is desirable to perceive. For example, separation between adjacent value positions may be greater than 10 times larger than a span associated with a value position.

In at least one example embodiment, it may be desirable to provide continuous value positions and indexed value positions for the same setting. For example, a focus setting may have a range of values associated with manual focus adjustment are conducive to continuous distribution. In such an example, a focus setting may have discrete values associated with designation of values that are not conducive to continuous distribution, such as infinity focus, associated with operations for controlling focus, such as automatic focus, or hyper focus. In at least one example embodiment, a slider interface element comprises a continuous region and an indexed region. In at least one example embodiment, a continuous region relates to a region associated with a continuous value position distribution. In at least one example embodiment, an indexed region relates to a region associated with an indexed value position distribution. In at least one example embodiment, overlap of a continuous region and an indexed region is precluded. In at least one example embodiment, a value position within an indexed region is referred to as an index.

In at least one example embodiment, it may be desirable to allow the user to move a selection point relative to a slider interface element in a continuous manner without regard for correlation between a value position and the selection point. In at least one example embodiment, it may be desirable to automatically move a selection point relative to a slider interface element in circumstances where a value position fails to align with the selection point, after an input associated with adjustment of the setting is performed. In at least one example embodiment, this adjustment movement based, at least in part, on lack of correlation between a value position and a selection point may be referred to as snap-to movement.

In at least one example embodiment, a slider interface element comprises at least one demarcation signifying at least one index of the indexed region. A demarcation may be a delineation indicating the index, a value indicator, such as indicator 230 of FIG. 2B.
